Product Details:

We are certain you've seen these plasma balls before. They've
been around ever since bad hair bands from the eighties. Recently
they've become available in tech friendly USB versions so we've
decided to put this classic on your must have list. Our only
question really is why can't we have amazing, affordable, *NEW*
desktop science toys invented in the twenty first century? Things
like mini USB desktop wormholes, or keychain Schroedinger's kitten
boxes? If you can't give us jetpacks, at least make some for our
action figures...

But ThinkGeek, How does the USB Plasma Ball Really
Work?
Glad you asked. A combination of interesting and fun gasses (like
Argon) are first trapped inside a plastic sphere at relatively low
pressures. An alternating current, at relatively high voltages
(Hey, this is USB remember, so it can't get too crazy), are pumped
into the sphere via an electrode in the center. This energy causes
electrons to be stripped from the gasses,leaving in its wake some
positively charged ions and a gorgeous gaseous and electrically
conductive environment (aka Plasma). That high voltage served up
through the electrode will now arc up through the plasma to the
lower voltage edge of the plastic sphere (starting at the t(more...)
